ECD SYSTEM(w/ DPF), Diagnostic DTC:P0617

DTC Code DTC Name
P0617 Starter Relay Circuit High

DESCRIPTION

While the engine is being cranked, positive battery voltage is applied to terminal STA of the ECM.

If the ECM detects the starter control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The ECM then illuminates the MIL and stores the DTC.

This monitor runs when the vehicle has been driven at 20 km/h (12.4 mph) or more than 20 seconds.

P0617
DTC Detection Drive Pattern DTC Detection Condition Trouble Area

Conditions (a), (b) and (c) are met for 20 seconds (1 trip detection logic):


  • (a) Vehicle speed is more than 20 km/h (12.4 mph).

  • (b) Engine speed is more than 1000 rpm.

  • (c) STA signal is on.

  • Starter relay assembly circuit

CAUTION / NOTICE / HINT

Note


  • When replacing the ECM, the ECM needs Registration and Initialization Click here.

  • Inspect the fuses for circuits related to this system before performing the following inspection procedure.

Tech Tips


  • The following troubleshooting process is based on the premise that the engine can crank normally.

    If the engine does not crank, proceed to the Problem Symptoms Table Click here.

  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing a new ECM, perform all of the initialization and registration procedures for the "Learning Values Write" function by following the instructions shown on the GTS display.

  • Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

PROCEDURE


  1. READ VALUE USING GTS (STARTER SIGNAL)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List / Starter Signal.

    5. Check the value displayed on the GTS when the vehicle is driven at 20 km/h (12.4 mph) or more.

      Note

      When performing the confirmation driving pattern, obey all speed limits and traffic laws.
